  • the present invention relates to an improved construction for an encapsulated three-phase high voltage line whose phase conductors are arranged on three insulators arranged in one plane within a grounded metallic tubular casing filled with insulating gas under pressure.
  • Such arrangements of a high voltage line are known, for example, from German Pat. No. 949,670.
  • the three-phase conductors are carried at the inner ends of three supporting insulators having an angular spacing of 120 about the axis of the casing which in turn are secured by their outer ends directly on the inner face of the tubular casing.
  • Such an arrangement is suitable only for relatively short conductor bar lengths, in particular for bus bars in encased circuit systems.
  • the high voltage line can then be assembled only in a section-by-section manner,machining of the casing being required for the attachment of the supporting insulators, owing to which a relatively high production cost results.
  • the present invention has for its principal object to provide a solution where there is no real mechanical and structural dependence between the phase conductor system and the tubular casing.
  • this is achieved in that the three insulators carrying the phase conductors are secured to the inner sides of longitudinally spaced carrying rings which include on their outer surface projections which enable the carrying rings to be guided within the tubular casing.
  • the tubular casing becomes a simple pipe which requires no machining of any kind for the support of the phase conductor system, since the latter and the tubular casing constitute two separate structional components.
  • the three-phase conductor system constitutes a separately portable assembly which can be mounted, tested, and transported independently of the outer casing.
  • FIGS. la and 1b show in transverse and longitudinal section respectively ahigh voltage line withthe threephase conductors arranged in an equilateral triangle;
  • FIG. 2 shows somewhat more schematically a longer line section similar to FIGS. la, llb but which is bulkheaded at intervals as to gas, and
  • FIG. 3 shows in transverse section a form of the encased high voltage line for use as bus bar.
  • the outer, grounded tubular casing which can be of any length is illustrated in the form of section 1,1 which abut and are welded together gas-tight by means ofa pipe sleeve 11.
  • the phase conductors 2,3,4 which are oriented 120 apart about the casing axis are surrounded and firmly connected by means of ring armatures 9 with the inner ends of insulators 6,7,8 spaced 120 apart and the latter are in turn secured at their outer ends to the inner surface of the carrying ring 5.
  • the carrying ring may be made of metallic material or of insulating material and includes on its outer surface projections 10 which may be designated either as sliding or rolling bodies and serve to guide the carrying ring within the outer tubular 1.
  • Three projections 10 from ring 5 of equal height which are spaced uniformly about the circumference of the ring, can, for example, be located respectively at each of the three insulators 6 to 8, and a circle circumscribing and touching the radially outermost points on the three projections which is concentric with ring 5 has a diameter less than that of the inner surface of the cylindrical casing 1.
  • FIG. la depicted in FIG. la, and likewise in FIG. 3 discussed below but wherein the projections 10 are not located in radial alignment with the conductor support insulators, when rings 5 are in position inside of easing 1, two of the three projections 10 rest upon the inner surface of the casing 1 while the third projection stands clear.
